Non-specific immunity, or innate immunity, is the immune system with which you were born, made up of phagocytes and barriers. Phagocytosis , derived from the Greek words phagein , meaning to eat, kytos or cell, and “osis” meaning process, was first described by Élie Metchnikoff , who won the Nobel Prize 100 years ago.
The innate immune system or nonspecific immune system [1] is one of the two main immunity strategies in vertebrates (the other being the adaptive immune system). The innate immune system is an alternate defense strategy and is the dominant immune system response found in plants , fungi , prokaryotes , and invertebrates (see Beyond vertebrates ).
Some publications point towards the effect of deoxycholic acid (DCA) as an immunostimulant [9] [10] [11] of the non-specific immune system, activating its main actors, the macrophages. According to these publications, a sufficient amount of DCA in the human body corresponds to a good immune reaction of the non-specific immune system.
Innate immune defenses are non-specific, meaning these systems respond to pathogens in a generic way. [19] This system does not confer long-lasting immunity against a pathogen. The innate immune system is the dominant system of host defense in most organisms, [2] and the only one in plants. [20]
"As a natural immunosuppressant, chronically-high cortisol can put us at risk for a weakened immune system." So beyond a more nutritious diet and active lifestyle, these immunity tips below are ...
Respiratory virus season is officially here in the U.S., making it a prime time to catch a cold. And because the average adult gets two or three colds a year, you could be dealing with an ...
This material is then displayed to other cells of the immune system. Some phagocytes then travel to the body's lymph nodes and display the material to white blood cells called lymphocytes. This process is important in building immunity, [13] and many pathogens have evolved methods to evade attacks by phagocytes. [14]
